Subject: [Sip] ABNF rule used in RFC 4244

Hi,

In RFC 4244 (An Extension to SIP for Request History Information) there is the following ABNF rule:

hi-index = "index" EQUAL 1*DIGIT *(DOT 1*DIGIT)

DOT is not defined as an ABNF core rule in RFC  4234 (ABNF) and is not defined as a basic rule in RFC 3261.

It is only used and defined in RFC 3525 (Gateway Control Protocol Version 1).

Is it defined elsewhere?

This could be a problem for parsers.

This rule should be:

hi-index = "index" EQUAL 1*DIGIT *("." 1*DIGIT)

Regards

Joël
